FASTENER.

Patented Sept. 2,1913.

Serial No. 690,328.

To all 'u /zom it may concern lie it known that T, Gnonon N. 'lo'mrnms, a citizen of the United States, and a resident of Croton on Hudsoinin the county of estchester and State of New York, have invented a new and Improved Fastener, of which the following is a full, clear, and exact description.

My invention relates to fasteners, and it has for its object to provide one with a member in which three radiating cuts are made, the edges of the member at one of the cuts being rolled back to form an opening, in which a pin may be disposed.

Additional objects of the invention will appear in the following complete specitication, in which the preferred form of the invention is disclosed.

In the drawings similarcharacters of reference indicate corresponding parts in all the views, in which Figure 1 is a plan view, showing how the three radiating cuts are made; Fig. 2 is a view on the same plane, after the edges of the plate at one of the cuts are rolled back, to form the fastener; Fig. 3 is a sectional view on the line 3-3 of Fig. 2, with the pin. disposed in position in the fastener; and Fig. t is a sectional view on the line 4-4 of Fig. 2.

By referring to the drawings it will be seen that a plate 5 is provided, in which cuts 6, 7 and 8 are made, these cuts radiating from a central point 9. The edges 10 at the cut 6 are then rolled back with the edges 11 rolled longitudinall of the cuts 7 and 8, to form the fastener shown in Figs. 2, 3 and l of the drawings.

The fastener having been constructed as stated, another plate 12 having a pin 13, seoured thereto, is disposed under the plate 5, so that the pin 13 may project through the opening 14, adjacent the central point t), the pin 13 being locked relatively to the plate 5 when it is moved to the left, the rolled portions 10 of the plate engaging the head 1:") to prevent the pin 13 from becoming free from the plate 5 until the pin is again moved to the end adjacent the central point 9.

This fastener can be manufactured very cheaply and it is exceedingly strong and durable.

It will be understood that as the edges 10 of the plate where they meet the edges 11 aredisposod farther away from the plane of the plate than the edges 10 at the left of the cut (3, the pin 13 will travel to the left of the cut, and away from the central point 9 in the plate 5, when, there is a strain on the pin 13 away from the plate 5. It will also be seen that the point 9 will serve to prevent the pin 13 from traveling in or between the cuts 7 and S, and also to the right beyond the highest portions at the right of the rolled edges 10.

As the plate 5 is preferably of resilient metal, the rolled edges 10 may be sprung away from each other to permit the passage of a head on a pin, which is greater in diameter than the normal distance between the two rolled edges 10.

I'l aving thus described my invention I claim as new, and desire to secure by Letters Patent:

1. In a fastener, a metal plate in which three cats are made radiating from a point, triangular portions of the metal plate being rolled back from one of the cuts, and longitudinally of the other cuts.

2. In a fastener, a metal plate in which three cuts are made radiating from a point, triangular portions of the metal plate being rolled back from one of the cuts, and longitudinally of the other cuts, and a pin adapted to be disposed in the opening made by the rolled portions of the metal plate, and a head on the pin for engaging the rolled portions of the plate.

In a fastener, a resilient plate, in which three cuts are made, radiating from a point, the edges of the resilient plate being rolled back from a point at the outer end of one of the cuts, and longitudinally of the other cuts, to form a triangular opening having as its apex the secoud-nientioned point.

4-. in a fastener, a resilient metal plate, in which two cuts are made radiating from a point, a triangular portion of the resilient metal plate being rolled back from one of the cuts, and longitudinally of the other cut, to form a triangular opening.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
